Method Detail

isId

public boolean isId()

Is the attribute an id attribute. This method will return true if the attribute is an attribute that corresponds to a simple id, an embedded id, or an attribute of an id class.

Specified by:

isId in interface SingularAttribute<X,Y>

Returns:

boolean indicating whether the attribute is an id

isVersion

public boolean isVersion()

Is the attribute a version attribute.

Specified by:

isVersion in interface SingularAttribute<X,Y>

Returns:

boolean indicating whether the attribute is a version attribute

isOptional

public boolean isOptional()

Can the attribute be null.

Specified by:

isOptional in interface SingularAttribute<X,Y>

Returns:

boolean indicating whether the attribute can be null

getType

public Type<Y> getType()

Return the type that represents the type of the attribute.

Specified by:

getType in interface SingularAttribute<X,Y>

Returns:

type of attribute

isAssociation

public boolean isAssociation()

Is the attribute an association.

Specified by:

isAssociation in interface Attribute<X,Y>

Returns:

boolean indicating whether the attribute corresponds to an association

isCollection

public boolean isCollection()

Is the attribute collection-valued (represents a Collection, Set, List, or Map).

Specified by:

isCollection in interface Attribute<X,Y>

Returns:

boolean indicating whether the attribute is collection-valued

getBindableType

public Bindable.BindableType getBindableType()

Return the bindable type of the represented object.

Specified by:

getBindableType in interface Bindable<Y>

Returns:

bindable type

getBindableJavaType

public Class<Y> getBindableJavaType()

Return the Java type of the represented object. If the bindable type of the object is PLURAL_ATTRIBUTE, the Java element type is returned. If the bindable type is SINGULAR_ATTRIBUTE or ENTITY_TYPE, the Java type of the represented entity or attribute is returned.

Specified by:

getBindableJavaType in interface Bindable<Y>

Returns:

Java type
